To all whom it may conccrn:

Be 'it known that I, JOHN TV. WINGETT, a citizen of the United States, residing at Washington, in the County of lVashington and State of Pennsylvania, have invented new and useful Improvements in Tubing Protectors, of which the following is' a specificaton.

This invention relates to protecting devices, and more particularly to means for protecting the tubing of oil and gas wells.

One of the main objects of the invention is to provide simple and eiiicient means whereby the casing head. and gas line of an oil or gas well are effectively enclosed by heat insulating material so as to prevent eXcessive heating and igniting` of the gas or oil in the event of the derrick catching fire. A further object is to provide a device of the character stated which may be quickly and easily applied. Another object is to provide a device adapted to permit ready access to the casing head when necessary. Another object is to provide a device in which heating of the upper end of the tubing and the casing is efl ectually prevented thue eliminating possibility of the tubing and casing becoming detachedfrou the head and dropping into the well, such as frequently occurs where the upper end of the casing and tubing, and the casing head is subjected to great heat and is then cooled. Further objects will appear froni the detailed description.

In the drawingszv Figure l is a side View of a protector constructed in accordance with my invention as applied;

Figure 2 is a central vertical section through the same; r

Figure 3 is a top planiview of the lower section of the casing.

The device is intended to be used in connection with a casing head a of any suitable or preferred type provided in its upper cylindrical recess b within is provided with a joint including a collar e positioned above and resting upon disc c. Casing f is threaded into the *lower end of head a and communicates at its upper end with a gas receiving chamber g positioned beneath disc 0. Gas pipes h communicate with the chamber g at opposte sides thereof. In a'pplying the devce a suitable pit is i Specification of Letters Eatent.

dug beneath the derrck floor and receives? dug to the desired depth, member 4 is placed 'over the casing head a and is moved down wardly along well casing f to the bottom of the pit upon which it rests The plates 5 rase upwardly and outwardly within member 4 to accommodate passage of this member over the casing head, and drop inwardly so as to fit about well casing f when member 4 is below head a. As will be understood, member 4 is placed in position before the gas pipes h, are threaded into thecasing head. After member 4 is in position, body 2 of the casing is placed in position and attached to member 4.' `After this has been done the gas pipes h are threaded into the casing head, body 2 ofthe casing being provided with openings to accommodate these pipes. After sections and 4 of the 'casing have been placed in position, a top section 7 is placed about the upper portion of body 2 and forms therewith a cylindrical casing extending an appreciable distance above the casing head (Land collar e. The casing thus produced is then filled with a mixture of water and clay, or any other suitable refractory' material which, when set, forms a thick cylinder completely enclosing the casinghead andassociated parts and exhead and the parts associated therewith in' the event that the derrick burns down. By preventing this heating of the casing head and associated arts I eliminate possibility of the well casng or tubing becoming detached and dropping into the' well in the event of burning of the derrick, such as frequently occurs in structures now commonly in use. By removing upper section 7 of the casing, the material enclcsed by this sec ti on may be readily removed thus permitting ready access to the upper portion able bottom plates adapted to fit' about the' Well casng, a body member fitting into said lower member, and an upper member fittng about the uppe' portion of said. body member, all of said members co-operatng to form a cylndrcal casng dsposed con'centrc With the Well casng and extendng above and below the casng head, said cylndreal member being filled With refractory material surrounding the Well casng and the tubng above the head 'and completely enclosng said casng headend assocated parte In testmony Whereof I affix my signature.
